Junit5 参数化测试尝试时，Java 异常未找到匹配的测试

标签 java junit5 parameterized-tests

所以我尝试使用 JUnit5 中的 ParameterizedTest 并设置 pom 以加载所有内容，现在有以下测试类。

    import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.equalTo;
import static org.hamcrest.Matchers.is;
import static org.hamcrest.Matchers.not;
import java.util.stream.Stream;
import org.junit.Test;
import org.junit.experimental.categories.Category;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.Arguments;
import org.junit.jupiter.params.provider.MethodSource;
import org.junit.platform.runner.JUnitPlatform;
import org.junit.runner.RunWith;
import com.tdameritrade.ctg.cashmovement.enums.transaction.TransactionProcessEnum;
import com.tdameritrade.ctg.cashmovement.enums.transaction.TransactionStatusEnum;
import com.tdameritrade.ctg.junit.categories.UnitTest;

/**
 * Test class for Posting Common Utils
 */
@RunWith(JUnitPlatform.class)
@Category(UnitTest.class)
public class PostingCommonUtilsTest {

    private static Stream<Arguments> dataSetForTransactionStatus() {
        return Stream.of(Arguments.of(TransactionStatusEnum.ERRORED.getName(), true),
                         Arguments.of(TransactionStatusEnum.COMPLETED.getName(), false));
    }

    /**
     * Test method for
     * {@link com.tdameritrade.ctg.cashmovement.posting.PostingCommonUtils#checkTransactionErrored(java.lang.String)}.
     */
    @ParameterizedTest
    @MethodSource("dataSetForTransactionStatus")
    public void testCheckTransactionErrored(final String status, final boolean result) throws Exception {
        assertThat(PostingCommonUtils.checkTransactionErrored(status), is(equalTo(result)));
    }
}

我收到以下错误:

java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=testCheckTransactionErrored], {ExactMatcher:fDisplayName=testCheckTransactionErrored(com.tdameritrade.ctg.cashmovement.posting.PostingCommonUtilsTest)], {LeadingIdentifierMatcher:fClassName=com.tdameritrade.ctg.cashmovement.posting.PostingCommonUtilsTest,fLeadingIdentifier=testCheckTransactionErrored]] from org.junit.internal.requests.ClassRequest@654f0d9c

也许我错过了它，但我已经尝试搜索此错误，并且我发现的所有内容都指向已经设置的内容。比如有一篇文章说pom不在一起是对的，但是我有一样的东西。

这是我的 pom.xmls:

怎么了？

如果我通过命令行运行，这是错误的堆栈跟踪:

最佳答案

从您的堆栈跟踪来看，您似乎正在尝试使用 org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader 启动 JUnit 5 测试。这不太可能奏效，同样的问题as reported in this question .

尝试使用 Maven 从命令行运行测试，如 Running a Single Test 中所述文档:

mvn -Dtest=PostingCommonUtilsTest test

如果测试成功运行，或者您看到与 Eclipse 中完全相同的异常，那么说明您的 Eclipse 设置是正确的，这是框架的问题。否则，您的 Eclipse 设置存在缺陷并且不支持 JUnit 5。

这可能是 Eclipse 版本的问题。据官方Embracing JUnit 5 with Eclipse页:

We do not support running tests in a setup where an old Eclipse build (not having JUnit 5 support) is using a new Eclipse build (having JUnit 5 support) as target. Also, developers who have the JDT JUnit runtime bundles (org.eclipse.jdt.junit.runtime, org.eclipse.jdt.junit4.runtime) checked out and pull the latest changes will run into the above issue. You are expected to use a new Eclipse build for the development.
